vMy invention has for its object to furnish an improved coupling for connecting thills or a pole with the axle of a carriage, which shall be simple in construction, convenient in use, and safe and reliable in operation. The invention consists in an improved thill-eouplin g, formed by the combination of the slotted bar, the hook thill-iron, and the retainer with each other, as hereinafter fully described.

A represents a bar attached to the carriageaxle, and which Amay be the yoke of an axleclip. The forward end of the bar A is slotted or notched to receive the thill-iron B, and to t-he ears thus formed is attached a bolt, C, which may have a tubular rubber washer, D, placed upon it to prevent rattling. The head of the thill-iron B is made with a deep transverse notch or slot in its under side to t upon the bolt C, the hook thus formed being made of snfcient strength to sustain the draftstrain. E is the retainer, which is a small bar of iron, the ends of which work in slots formed in the bar A, an'd which, when pushed into the forward ends ot' its slots, comes so far over the l1ookhead of the thill-iron B as to prevent the said thill-iron from being raised from the bolt G without iirst pushing back the said retainer E. The retainer is held forward by a spring, F, of rubber or other suitable material attached to the bar A, and which will the displacement of the thill-iron, substa-ntially as shown and described.
